我正在尝试在我现有的 MVC5 项目上安装 ElmahR。在安装 ElmahR 之前，我使用 Elmah 和 NLog 来处理异常。根据本教程，我使用 nuget 包安装了 ElmahR

Install-Package ElmahR.Elmah

然后在 web.config 中，我更改了这一行：

<errorPost targetUrl="http://TARGET_DASHBOARD_URL" sourceId="SOURCE_IDENTIFIER_URI_AS_LISTED_IN_DASHBOARD_CONFIG" secret="SECRET_PASSPHRASE_(SPECIFY_JUST_IN_CASE_OF_ENCRYPTED_POST)" />

进入

<errorPost targetUrl="http://localhost:62335/posterror.axd" sourceId="MyCode" />

下一步我安装了仪表板

Install-Package ElmahR.Modules.Dashboard

并更改了这一行：

<application name="Sample application" sourceId="SomeCode" infoUrl="http://localhost:12345/elmah.axd" testExceptionUrl="http://localhost:12345/elmah.axd/test" />

进入

<application name="WPS" sourceId="MyCode" infoUrl="http://localhost:62335/elmah.axd" testExceptionUrl="http://localhost:62335/elmah.axd/test" />

在 HomeController (Index) 中，我生成错误throw new exception("Test ElmahR");并运行。然后我去http://locahost:62335/elmahr/dashboard看看没有捕获到异常，但是如果我看到http://localhost:62335/elmah它捕获到错误“未找到路径'/posterror.axd'”而不是测试 ElmahR。为什么？

正如@Wasp 的建议，我在system.webAND中注册了 Elmah 模块和处理程序，system.webServer但仍然没有解决问题：

<system.web>
  ...
  <httpHandlers>
    <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
  </httpHandlers>
  ...
</system.web>

<system.webServer>
  ...
  <handlers>
    <add name="Elmah" verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
  </handlers>
  ...
</system.webServer>

If you are NOT using IIS (Full or Express), you might have the issue because I do not see the system.web/httpHandlers section in your web.config, which is where you would declare the missing posterror.axd endpoint. The endpoint is there in the system.webserver/handlers section, but that requires IIS. Did you check that?
